 * For an Expo-hosted project with a manifest hosted at https://expo.io/@user/project/index.exp, the
 * base URL would be https://expo.io/@user/project.
 *
 * We also normalize the "exp" protocol to "http" to handle internal URLs with the Expo schemes used
 * to tell the OS to open the URLs in the the Expo client.
